Problems solved by technology
The hot blast stove currently used mainly includes a furnace body and a furnace cover. Due to structural reasons, there are the following defects: First, the hot blast stove has low efficiency and serious energy waste
The heat exchange area of the air on the outside of the furnace body is small, the heat exchange efficiency is low, the cost is increased and air pollution is easily caused
Second, the structure is complex and the process performance is poor
The furnace body is difficult to disassemble and assemble, it is not convenient for maintenance and daily maintenance, and the deposited soot cannot be cleaned, which affects the service life

The invention discloses a hot blast stove. The top of the furnace body is provided with a first gas outlet and a gas inlet, the bottom of the furnace body is provided with a plurality of through holes, the lower part of the side wall of the furnace body is provided with a second gas outlet, and the furnace head is located at the bottom of the furnace body. , the combustion chamber in the furnace head communicates with the outside through the through hole at the bottom of the furnace body, the heat dissipation structure is located in the furnace body, and the inside of the heat dissipation structure is provided with a flue gas channel that penetrates up and down, and the top of the flue gas channel communicates with the outside through the first gas outlet, and the smoke The bottom of the gas channel communicates with the combustion chamber of the furnace head, a gas channel is formed between the heat dissipation structure and the inner wall of the furnace, and the gas inlet of the furnace body communicates with the second gas outlet through the gas channel. In the hot blast stove proposed by the present invention, a plurality of cylindrical heat dissipation units are connected in sequence to increase the heat exchange area, so that the heat exchange between the flue gas in the flue gas channel and the gas in the gas channel is more sufficient, greatly improving the heat exchange efficiency, and at the same time facilitating the heating of hot air. Furnace overall maintenance.
Description
technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a hot blast stove. Background technique [0002] As a thermal power machine, the hot blast stove began to be widely used in our country in the late 1970s. It has become a replacement product for point heat sources and traditional steam power heat sources in many industries. In the fields of food, pharmacy, heating, etc., for the drying of items, a dryer that feeds dry high-temperature hot air is generally used, and the dry high-temperature air is mainly generated by a hot blast stove. The currently used hot blast stove mainly includes a furnace body and a furnace cover, and has the following defects due to structural reasons: First, the hot blast stove has low efficiency and serious energy waste. The heat exchange area of the air outside the furnace body is small, the heat exchange efficiency is low, the cost is increased and air pollution is easily caused. Its two, ...
